Problems solved by technology

However, this treatment cannot be transferred to saddle coils made of thin-layer HTSL, because the HTSL thin layer would be overstretched when winding the winding body, ie the superconducting thin layer would break at least in the upper region of the strip, at least partially ruptured

Embodiment Construction

[0030] figure 1 The armature in includes a hollow cylinder 11 on which eight saddle coils 10 are arranged at equal intervals. Each saddle coil 10 has two coil ends 10.1 and two longitudinal sides 10.2. The connection of the saddle coil 10 , the cooling structure of the coil and the support structure of the armature as well as other details concerning the armature have been omitted for the sake of clarity.

[0031] figure 2 A cross-sectional view of an armature shown in FIG. 1 but comprising a saddle coil 20 according to the invention is shown. This section is perpendicular to the axis of rotation and lies in the region of the longitudinal sides of the saddle coil 20 . Eight saddle-shaped coils 20 are installed on the hollow cylinder 1, and these saddle-shaped coils 20 are image 3 Shown enlarged. The saddle coils 20 each comprise a saddle coil winding body and a saddle coil winding 23 made of strip-shaped thin-layer HTSL, which is also called an HTSL winding or simply a ...

Abstract

The invention relates to a winding body (80) including a winding support (85) between a first plate (82) and a second plate for a saddle coil winding made from a thin layer HTSC, which is destined for a cylindrical armature of an electrical machine, and which has two longitudinal legs parallel to the armature axis between two winding ends, wherein the winding support for each winding end has a bearing surface (85.1); if the area in the longitudinal direction between the first plate (82) and the second plate is a hollow barrel section matching with the surroundings of the armature and each bearing surface (85.1) of the winding end is such twisted that the length difference between the upper edge (85.13) of the bearing surface (85.1) and the lower edge (85.12) of the bearing surface divided by the quotient of the width of the bearing surface (85.1) and average edge length of both edges (85.13, 85.12) is at most corresponding to curvature about 3 degrees per meter, the thin HTSL can be wound into the saddle coil without damaging the HTSL thin layer.

Description

technical field [0001] The invention relates to a winding body with a winding former between a first plate and a second plate for saddle coil windings made of strip-shaped thin-layer high-temperature superconductors (HTsL) and used as Cylindrical armatures of electrical machines such as electric motors. Background technique [0002] So far, saddle coils for electromechanical rotors or armatures have been wound from wire-shaped conductors with a circular cross-section. However, for reasons of production technology, the high-temperature superconductors are preferably tape-shaped, that is to say they have a distinctly rectangular cross-section. Such tape-shaped HTSLs usually consist of a metal substrate tape on which is applied a material made of, for example, YBa 2 Cu 3 o 7-x (YBCO) ceramic HTSL thin layer. These HTSLs are also known as thin-layer HTSLs. Unlike tape substrates, thin layers of ceramic HTSLs have little elasticity. Therefore, the bending of the ribbon thin...
